AI Article Synopsis

  • A high-frequency ultrasound was used to detect a nonpalpable etonogestrel implant located in the biceps muscle, positioned 4-6mm beneath the skin.
  • When the elbow was actively flexed, the implant moved closer to the ultrasound probe, indicating it was situated within the muscle.
  • This technique could help confirm that the implant is intramuscular before any surgical removal is performed.

Article Abstract

A nonpalpable etonogestrel implant was identified by high-frequency ultrasound in the biceps muscle 4-6mm below the skin. Active elbow flexion resulted in proximal movement of the implant relative to the ultrasound probe, suggesting localization in the muscle. This maneuver may assist in verifying intramuscular placement prior to surgical excision.

Objective: This study aimed to investigate the e!ect of arthroscopic Bankart repair (ABR) alone and ABR with an additional remplissage procedure on joint range of motion and functional results in patients with anterior shoulder instability.

Methods: This retrospective study included patients treated 1 year ago with either ABR alone or the ABR additional remplissage procedure. The Bankart lesion was determined by magnetic resonance imaging, and the amount of glenoid bone loss was determined by computed tomography.

Some technical limitations to using the eccentric mode to measure peak eccentric strength of the hamstrings (PTH) were raised. PTH also has limited validity to predict performance or injury risk factor. Therefore, our aim was to compare PTH and other isokinetic variables tested in the eccentric and passive modes.

The aim of this study was to investigate the effects and potential mechanisms of 8-week transcranial direct-current stimulation (tDCS) combined with resistance training (RT) on pull-up performance in male college students. Twenty-five male college students were randomly assigned to either RT combined with anodal tDCS stimulation (RT + tDCS) or RT alone (RT). Participants of both groups engaged in lat pull-down training programs for 8 weeks, with the RT + tDCS group receiving 20 min tDCS before each RT session.

Purpose: Ligamentous elbow dislocations often affect young patients with high functional and athletic demands. After reduction and clinical examination of joint stability, further treatment options are, therefore, the subject of controversial debate. In order to be able to advise patients adequately, an assessment of the possible return-to-sport based on experience is necessary.

Introduction: Blunt brachial artery injuries (BAI) require reconstruction with an extensive vein graft due to the wide area of arterial damage. In the upper arm, safe options for pedicle flaps are limited, and selecting recipient vessels for free-flap surgery is challenging, complicating the treatment of soft tissue injuries associated with blunt BAI. This study aimed to analyze the characteristics and soft tissue reconstruction of blunt BAI and propose treatment strategies for treating associated soft tissue injuries.
